Solid phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid (polymer) or a solid (sorbent), [1] which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid ...

Solid phase microextraction (SPME) is a solvent-free sample preparation technology. Based on the principle of adsorption or absorption and desorption, SPME uses a coated fiber or Arrow to concentrate volatile and semivolatile compounds from a sample.

Solid phase microextraction (SPME) is a non-exhaustive sample preparation technique in which a small volume of extractive phase (immobilized on a solid support) is exposed to the sample for a well-defined period of time. From: Analytica Chimica Acta, 2015

Solid phase microextraction (SPME) is an innovative and sensitive solvent-free sample preparation technology. Based on the principle of adsorption/absorption and desorption, SPME uses a coated fiber to concentrate volatile and semi-volatile compounds from a sample.

Solid Phase Microextraction (SPME) is a fast, solvent-less sample extraction technique. It is used for extracting organics from a matrix (solid, liquid, or gaseous) into or onto a stationary phase immobilized on a fiber. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and a polymer-coated fused fiber.

2023年7月12日 · Solid phase micro-extraction, is a solvent less sample preparation technique introduced by Belardi en Pawliszyn in 1989 [1]. In SPME, an easy-to-use device containing a coated fiber to concentrate volatile and semi-volatile organics extracts target analytes from the matrix in one step. SPME consists of two processes:

2022年8月1日 · Solid-phase microextraction (SPME) has become a powerful sample preparation technique which allows to efficiently isolate and enrich analytes from complex matrixes. One of the most widespread SPME modes, consists of the extraction directly from the headspace (HS) which is equilibrated with the sample.
